A new exhibit at the Getty Museum in Los Angeles titled “Rising Signs: The Medieval Science of Astrology” explores the historical use of astrology in health practices and medical treatments. According to medieval astrologers, October is a time for battles, while November is best for gathering acorns. These insights are part of a fascinating look at how astrology shaped daily life during the Middle Ages.

For centuries, astrology was an integral part of academia in Europe, intersecting with fields like medicine. Kings often consulted court astrologers for guidance on matters of state and warfare. The belief was that the positions of celestial bodies at birth could influence an individual’s health, with different zodiac signs linked to specific diseases. For instance, Geminis were thought to be more prone to respiratory issues, while Sagittarians faced muscle and joint ailments.

The Getty’s exhibit is attracting attention not just from history buffs but also from celebrities, including Andrew Garfield, who described the collection of illuminated manuscripts as “kind of dope.” However, some visitors are taken aback by the idea that their contemporary astrological signs might differ from medieval calculations.

Dr. Larisa Grollemond, the exhibit’s curator and assistant curator of manuscripts at the Getty, is currently penning a book on medieval wellness practices. In a conversation with the Guardian, she discussed how the perception of astrology has evolved, what surprises modern astrology enthusiasts when encountering medieval practices, and why she believes medieval people would have embraced Instagram. Here’s a look at their discussion:

**What are the main differences in how astrology is utilized today compared to medieval Europe?**

Dr. Grollemond: “Today’s astrology leans heavily toward personality traits, often revolving around romantic compatibility and interpersonal relationships. In medieval times, astrology had a more scientific foundation. It was seen as a serious discipline that helped interpret time’s passage and the celestial influence on health and lifestyle choices. It was more closely aligned with daily living: what to eat, how to care for oneself, and which activities were best suited for a specific time of the year.”

**How many people in medieval Europe were aware of their astrological signs?**

Dr. Grollemond: “It’s tough to pinpoint exactly. Astrology was certainly part of the intellectual discussions in universities and medical practices. Most people receiving medical treatment likely encountered some astrological concepts—whether related to bodily humors or the timing of bloodletting. However, it’s unlikely that every peasant knew their specific sign.”

**Did astrology play a role in medical treatments? Were patients ever asked about their signs?**

Dr. Grollemond: “Variety in medical practices existed. A barber-surgeon might perform bloodletting based on a detailed astrological analysis, while a folk practitioner might simply adhere to seasonal guidelines. Astrological concepts influenced both the timing and methods used in treatments, rooted in the belief that different signs governed various parts of the body.”

**The exhibit suggests that one’s astrological sign could differ from today’s interpretations. Why is that?**

Dr. Grollemond: “The medieval system connected each month with a specific zodiac sign in a simpler way. Our current astrological framework has evolved with precise astronomical observations, leading to more specificity in zodiac dates. This realization shakes some people’s identities; many see their sign as integral to who they are, while shifting to a historical perspective can be challenging.”

**Was there as much skepticism about astrology in the medieval period as exists today?**

Dr. Grollemond: “Astrology was widely practiced within royal courts and was respected for its influence on significant decisions. However, skepticism emerged regarding its usage for prophecy or divination, as such practices were sometimes viewed as overstepping divine boundaries. Medieval views on astrology were more nuanced than the outright dismissal seen today.”

**How did astrology coexist with Christianity in the Middle Ages?**

Dr. Grollemond: “Astrology often featured alongside religious texts. The interpretation of celestial movements aligned with a Christian worldview, suggesting that God’s design extended to the heavens and that understanding these placements was part of fulfilling His plans.”

**You recently engaged in a discussion with online astrologers. What are your thoughts on the generational shifts in astrology?**

Dr. Grollemond: “Recent events, like the pandemic, have prompted many to seek meaning in daily life, leading to a resurgence of interest in astrology, particularly among younger generations. It’s fascinating to consider how 600 years from now, people might perceive 2024 as a notable astrological moment.”

**What parallels do you see between historical and contemporary astrology?**

Dr. Grollemond: “The print revolution in the late 15th century made astrological texts more accessible, similar to today’s social media and apps that spread astrology. Both periods saw a rise in public interest fueled by wider access to astrological information.”

**Do you believe medieval individuals would relate to modern online astrology content?**

Dr. Grollemond: “I think the average medieval person would thrive on Instagram. They would recognize many modern astrological symbols and concepts. However, they might struggle with contemporary interpretations of personality traits linked to zodiac signs.”

**What advice can medieval astrology offer for us this October and November?**

Dr. Grollemond: “In October, it’s a prime time for taking decisive actions—very much in line with Scorpio energy. Meanwhile, November, under Sagittarius, is excellent for activities like gathering acorns, harvesting, marriage, reconciliation, and even bloodletting—which people seem particularly interested in discussing these days.”
